Tessellation of the letter/symbol π in symmetry group p2. Only a special π (with leg length 6) fits in a rectangular cell. Currently displaying a version in 3 colours (the minimum map colouring) of red, yellow and blue with white outlines. This triples the cell and destroys the diad symmetry. Other colours, sizes and orientations are available on request and you can even ask for a combination of several designs together.
